My shack is built around an ICOM IC-7610.
I’ve never owned an HF amplifier and am limited to 100 watts. I’ve no plans to add an amplifier this year, but if and when I do it would likely be a 500 watt solid state amplifier like the KPA500 from Elecraft.
The 7610 has a built-in antenna automatic tuner but it’s inadequate for the wire antennas I generally employ. That’s why I also have an ICOM AH-4 auto-tuner. It’s been a great purchase and handles whatever oddball aerial I’ve thrown at it. ICOM says it “covers all amateur bands from 3.5 MHz through 50 MHz with a 23 foot or longer wire antenna” and I’ve found this accurate. It’s designed for a variety of locations, outdoors, on a back porch but mine is installed in the shack.
An IC-7300 serves as a dedicated digital station as well as a capable back-up for the 7610. Everyone knows about the 7300, it’s an excellent performer and probably the highest-value HF transceiver currently on the market. It integrates with the AH-4 to share the wire antennas, but I’m going to add a new vertical so these can be used simultaneously though I have no clue (yet) how to multiplex transceivers with logging and contest software.
Finally, I have an ICOM IC-9700 for all-mode VHF/UHF/1.2 work along with an Elecraft KX3 for field work though the KX3 can also serve as a back-up as it arguably has the best receiver in the shack. These two probably don’t factor in my DX Marathon quest, but they round out the station and provide me access from 160 meters to 1.2 Ghz as well as pick-up and go radio possibilities.
That’s the primary hardware line-up and I’m certain it’s more than adequate for my needs in this journey. The WORK is going to be integrating and automating as much of this as possible, and making it all friendly to operate.
